The V77 vertical machining center has been specifically designed to minimize thermal distortion for part precision and enhance higher quality finishes on die/mold output. The V77 provides environmentally controlled machine accuracy enhancements, such as Makino’s patented core-cooled, under-race lubrication system, which minimizes spindle distortion and twin shield-style splash guards to reduce the effect of temperature change in the factory. Available with either a 40-taper, 20,000-rpm or a 50-taper, 12,000/18,000-rpm spindle, the V77 can rough and finish hardened steel cavities/cores far more efficiently than general-purpose machines. Rigid linear guides and twin ballscrews are adopted for the Y-axis for a workpiece up to 5,500 pounds.
